Anyhow although I disagree with your opinion my question was asking WHY you see them as inappropiate for civilians to own . You don't HAVE to answer , but if you do so that is what I intended to ask .
Simply because there is no evidence that owning one of these will add to your safety. In the contrary, it can even reduce your chance to get out of a situation unharmed as pulling out a weapon in an already stressed situation surely won't calm anyone down.
So why exactly do you need a gun in the first place ? For that hilarious scenarios where you have to hunt to get something to eat or you have to fight "the goverment that turned against its own people" ?
Or just for sports, if so get yourself some darts.
